- Abstract
Background: The impact of gender on tumor necrosis factor inhibitors (TNFi) effectiveness has been poorly studied in Psoriatic Arthritis (PsA) patients. Objectives: To study gender differences in persistence and response of 1st TNFi in PsA patients. Methods: PsA patients prospectively followed at the Rheumatic Diseases Portuguese Registry (Reuma.pt), treated with a 1st TNFi, between 2001 and 2016. Drug retention assessed by Kaplan-Meier survival analysis and Cox models, adjusted for the year of starting a TNFi. Response rates measured by EULAR response, DAPSA remission, MDA and ASDAS response, applying LUNDEX method, were compared between genders. Baseline predictors of discontinuation and res - ponse were identified (Cox and logistic regression models). Results: 750 PsA patients, mean age 47.6 (± 11.6) years and 50.3% (n=377) females. PsA females showed significantly different baseline PsA disease characteristics in comparison with males and had more severe peripheral disease activity (Table 1). The overall TNFi survival rate for females was also significantly lower when compared with males. Additionally, females expe - rienced lower rates of response at 3 and 6 months (Figu re 1). Female gender was further identified as an independent predictor factor of worse persistence and showed a lower chance of good EULAR response. Conclusion: PsA females from Reuma.pt have distinct PsA features and worse persistence and response to a 1st TNFi in comparison with males. This might be related to gender dependent inflammatory pathways and was independent of baseline disease activity.
